Lower Intake Manifold Gasket
Exponent engineers and scientists assessed chemical compatibility of VMQ silicone and glass-filled nylon 6,6 materials for use in engine applications with exposure to hot coolant, oil and fuel. Types of analyses undertaken consisted of small scale laboratory evaluations of new and used gaskets (IR, SEM/EDS, Si29 NMR, GC/MS, compression testing, environmental exposures, etc.) all the way up to vehicle evaluations of temperature and pressure suitability, utilizing specially
instrumented engine components.
